Greetings from Lower Bavaria. last year I bought me a gpz 600 bj 86 and optically patched up the good piece again. new, tires, all fluids and candles I also donated. thanks to the workshop manual most reperatures and intervals are no problem. so far I have not driven a meter with the machine yet. after I have now brought the complete lighting back into operation, I started it today and found that it is only running on two pots ( 1 + 4). At the moment the left ignition coil (primary connection red and black) is connected to 2 + 3. according to whb, if I interpret the circuit diagram correctly, the ignition cables of the left coil go to 1 + 4. I now see the expl. drawing, then exactly the ignition cables of the right coil go to 1 + 4…. in the net has one times like this, the other times like this… I now have no idea what is right now. if I connect the ignition cables now according to circuit diagram – what happens then? maybe we know ß someone rat. gruss lars
